St. Mark's Basilica is a must-see for anyone visiting Venice. This stunning cathedral features incredible architecture, intricate mosaics, and immense history. Be prepared to wait in line for entry, but it is definitely worth it to see the gold leaf mosaics and Pala d'Oro, a golden altarpiece set with precious stones. If time allows, climb to the top of the Campanile for a breathtaking panoramic view of Venice.
Doge's Palace is a magnificent Gothic palace that was once the residence of the Doge of Venice. This stunning palace has served as a courthouse, prison, and government administration building throughout its history. Be sure to take a guided tour, as they offer insight into the palace's incredible art collection, its history, and its famous "Bridge of Sighs".
Rialto Bridge and Market date back to the 11th century and have been an important market and commercial district in Venice ever since. Take a leisurely stroll over the famous Rialto Bridge and explore the market, sampling fresh seafood, local produce, and traditional Venetian crafts. Be sure to stop and take in the view from the bridge, as it offers one of the most beautiful views of Venice's Grand Canal.
If you have more time, consider taking a gondola ride through Venice's famous canals or touring the Peggy Guggenheim Collection. For those with less time, skip the Rialto Bridge and Market and explore the neighborhood of Cannaregio instead. It's a great way to experience a more authentic side of Venice away from the crowds.
